Abstract: A microwave, one-half wave, coaxial cavity oscillator comprising a tubular cavity body having a section thereof constructed of a material having a high coefficient of expansion, a tube, an anode line having a section thereof constructed of a material having a low coefficient of expansion, and tuning member connected to an end plate of said body remote from said tube, which member forms an automatically variable capacitor with an end face of the anode line thereby to provide a variable capacitance responsive to operating temperature variations to minimize frequency deviations when the oscillator is operated under widely varying ambient temperatures. Another feature of the oscillator comprises a partition of high thermal conductivity connected between the anode line and cavity body to rapidly dissipate the heat generated by the tube, thereby to minimize the temperature gradient within the cavity body.
